WATER-BOILING ATTACHMENT FOR GAS-STOVES.

Specification of Letters Patent.

Patented Jan. 6,1914

Application filed March 14, 1912. Serial No. 683,889.

To all whom it may concern:

Be it known that I, CnAnLEs LEFEBURE, a citizen of the United States, residing at Chillieothe, in the county of Ross'and State of Ohio, have invented certain new and useful Improvements in Voter-Boiling At- .to utilize the heat normally generated in the oven'of the gas stove and to'simul't-a-neously be subjected to an independent flame external to .the gas stove and desirably playing upon the. attachment in such a manner as to insure heating of the water within a comparatively short time and without necessity for starting the main portion of the gas stove into operation.

My invention contemplates the provision of, a tank for containing water to be boiled, which may be readily placed in position or which is readily-dismountable and whicli'i's in such a position with relation to one of the walls of the gas stove oven as to give it benefit of the heating effect of such oven As hitherto stated, my inventitm contemplates the location of such tank in such a manner'uponjthe gas stove and the provision of a heatingflame of such atype, that. there is provided an auxiliary means for heating the fluid within the tank. My invention aims to provide such a structure of waterheating attachment that initial close proximity to the heated regions of the ovenmay be attained while, after dismounting of the attachment, the oven structure may be readily rendered complate in the sense that itis not unnecessarily disfigured by its assumption of such a shape as to readily receive the attachment.

The preferred embodiment of my invention is shown in the accompanying drawings, in which similar characters of refer- .enco designate corresponding parts, and in whichv Figure. l is a side elevation of gas stove with my attachment applied thereto, Fig. 2 is a view in section of. the end of a gas stove with my attachment applied thereto, such. attachment being, shown in section, Fig.- 3 is a top plan view of my attachment removed from the gas stove, Fig. -lis a longitudinal section taken through my attachment, and,

Fig. 5 is a detail view of a slide utilized for; complctimq the formation of the oven when my attachment isremoved therefrom.

In the drawings, the stove is shown at 1 .asmounted upon legs 2 and having an oven 3, which oven, as is the usual cvmslrueticm. is in communication with the flue pipe at.- tachment casting 4 for carrying the products of combustion into the line through the fine pipe (not shown).

The side or end of the gas stove 1 is desirably "provided with b 'aekets 5 and (3 which carry a shelf member 7 having an up- ;wardly extending ridge 8, which shelf is calcul: ted to form'a medium of support for the tank 9, being cut away desirably in circular form as atlO. The ridge 8 formed upon this shelf isdesigned to preventand ell'ectually prevent-s movement of thetank Sl *iatera'lly or longitudinally and the circular aperture 10 preferably comes above a burner 11 fed by a pipe 12 and under the. control of a cock 13. .This pipe may be 'heldor supported from the shelf by nieans of a bracket 14 with a supplemental brace 15.

The tank may be of varying, structure, but is desirably of substantially reetangula r form'having its upper end of a slightly greater width than its lower end aud provided with a seating rim 10 which supports asu erimposed top iece 17 having a downwar ly extending ll ange 18 and provided with a central'aperture 19 within which operates'a door 20 hingcdly mounted as at it and having a controlling handle as at 2; and depending ribs 20* on its two sides and frontedges and adapted to seal the door agaimtthis box-like's'trueture are desirably calkod with plaster-of-Paris or other suitable material to collect the sweat. There are two important features in the formation of this receptacle and one of these comprises a In teral ,enlargement23 formed upon one side of .the tank and constituting an integral portion thereof. This lateral enlargement is adapted to extend through an aperture :24 formed in the side of the oven and to thereby partially protrude into the nterior ofthe oven, whereby a portion oi? the oven heat is trmismitled directly through the wall of the tank. The other important l'ealure of my attachment compri es a li' \-lii e ll 1'- ture .23 mounted upon one end of the bot tom of the shell' 7 and having' its outer end closed as at 26,- while its inner end is open as at 27. This inner open end 27 is adjacent the heatin burner 11 and is calculated, by the naturfi draft created through the flue structure, to draw the products of combustion from the burner 11 thereintm The boxlike structure 25 desirably extends beyond the end of the. shelf member 7 and carries a delivery pipe 28 which preferably extends vertically and then laterally into the oven of the gas stove, as clearly shown in Fig. 2, from whence an exodus for the roducts of combustion is obtained throug structure in any desired manner. The draft from the oven of the gas stove due to the passage of the products of combustion through the flue attachment casting 4 and thence into the flue structure serves to create a draft in thepipe 28 and thereby in turn creates a tendency to the indrawing of the products of combustion from the burner 11.

It will be understood that the essential operations of the gas stove remain the same and that my device is simply an attachment thereto, which is readily removed, but which when in position may be rapidly heated to heat the material contained therein by means of'the heat'within the oven directly aflect-ing the enlargement upon the side of the tank: and by means "of the burner beneath the tank and blowing directly upon the bottom of the tank through the aperture 10.

When it is desired to remove my attachment from theoven structure, the tankneed.

'mal operation of the the flue the gas stove" is" completely closed as far as v the aperture 24= is concerned; It will thus be seen that I have provided stove which ma be applied or dismounted without materia ly interfering with the norgas stove.

*VVhat I claim, is-

In combination with a gas stove havinp an oven with an aperture in its side wal a' supporting shelf carried by the side of said oven below said aperture, a tank removably mounted on said shelf, an enlargement on the side of said tank adapted to fit into said opening when the tank is in position. on said shelf, a. gas jet disposed beneath said tank, a box-like structure having one end carried by said shelf adjacent sald gas jet, and a delivery pipe connecting said box-like structure with said oven where- .by the products of combustion from said gas jet are conveyed to said oven.

In testlmon whereof I aflix my signature .in presence 0 two witnesses.
